Product Summary

Aluminum cylinder block is an important kind of cylinder block. It can be easily learned that it is made of aluminum. The material is a soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminum is nonmagnetic and nonsparking. It is also insoluble in alcohol, though it can be soluble in water in certain forms. The yield strength of pure aluminum is 7–11 MPa, while aluminum alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminum has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

Besides, there are various series of aluminum cylinder block such as CB series, TMX series, YB series and so on. This Ford Cosworth YB aluminum cylinder block is a direct replacement for the Europ ean spec thick deck “200” iron block and can be used for 2wd or 4wd wet sump or dry sump applications . It is intended for normally aspirated or turbocharged engines. Cast from LM25 and heat treated to TF condition for uncompromising strength. The large , robust shot penned cast alloy main caps are located with precision ground ring dowels and s cured using a 12 mm high strength stud, washer, and nut kit. The thick - wall bores can accommodate dry iron straight ht thin wall liners in 90.8mm, 92mm, 94mm, and 96mm or the bores can be left unfinished allowing other liner types to be installed.

Additionally , crankshafts up to 88mm stroke with high performance rods are acceptable . The deck height is finish machined to original specification ( 207.5mm ) , but is also available with a 217.5mm deck for long rod and/or striker crank application. Unlike the iron block with limited material beneath the threaded head bolt/stud holes, this aluminum cylinder block features large cast pillars that extend internally from the deck to the crankcase portion of the block, which permit the threaded stud holes to be machined deep into the block.
